"2.4 kb deletion encompassing the first exon of the LAMC2 gene" (Murgiano et al., 2015)

Bourneuf et al. (2017) detected COL6A3 g.117453719G>A; p.T1894M; omia.variant:1184 as a de novo recessive potentially lethal mutation from an analysis of whole-genome-sequence of a Holstein AI bull. No information was provided on the descendants of this bull.

Syndactyly has been reported in many breeds of cattle in many countries. Most of the documentation, however, concerns its occurrence in US Holsteins, where, as a result of the siring of more than 60,000 calves by a bull who was subsequently shown to be a carrier, the disorder attracted considerable attention (Anon., 1967). The possibility that artificial selection favouring heterozygotes may have contributed to the unacceptably high frequency ...

In a neat piece of comparative detective work, Lunden et al. (2002; Genome Research 12:1885-1888) investigated whether the fishy off-flavour occasionally reported in cow's milk could be an animal model of fish-odor syndrome in humans, an inborn error of metabolism characterised by a fishy body odor, and known to be due to mutations in the gene for flavin-containing mono-oxygenase 3 (FMO3). They were able to show that this is, indeed, the case:...
